DISH-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 713,842, dated November18, 1902.

Application filed December19,190l. Serial No. 86,537. (Nomde1.)

T0 ctZZ whom it may concern:

Be it known that I, GEORGE S. BLAKESLEE, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Dish-\Vashing Machines,of which the following is a specification, reference being had to theaccompanyingdrawings.

My invention relates to washing-machines, and has particularly to dowith machines designed for washing dishes. It has for its object toprovide an improved machine by which dishes may be thoroughly andexpeditiously washed while they remain stationary or comparatively so.

Hcretofore dish-washing machines have been produced designed to wash thedishes without their being rotated or otherwise moved while in thewash-water; butsuch machines, so far as I am aware, have not beensatisfactory or successful, because they have not been so designed as toprovide for the thorough scouring of the dishes. By my in vention,however, I provide for forcing the wash-water up through the mass ofdishes and at the same time for directing it down upon them, producingvery violent agitation of the water in the tank, and insuring thethorough scouring of all the dishes under treatment.

A further object of my invention is toprovide certain improvements inthe agitating devices, in the means for directing the washwater downupon and through the dishes, in the dish-holding basket, and in variousother parts of the apparatus, all of which are fully hereinafterdescribed.

That which I regard as new will be set forth in the claims.

In the drawings, Figure 1 is a plan view, part of the drip-tray beingbroken away. Fig. 2 is a side elevation, some parts being in section.Fig. 3 is an end elevation, some parts being in section. Fig. 4 is anelevation of the dish-holding basket. Fig. 5 is a partial plan viewthereof. Fig. 6 is a perspective detail showing the devices for holdingthe bail of the dish-holding basket in its upright posi tion. Fig. 7 isa perspective view illustrating the deflectors and the frame in whichthey are carried. Fig. 8 is a perspective view showing thereinforcing-frame at the bottom of the deflector-frame. Fig. 9 is aperspective view showing the agitator in its simplest form. Fig. 10 is aperspective view showing the most improved form of agitator. Fig. 11 isa perspective View showing a part of the agitator illustrated in Fig.10, and Fig. 12 is an elevation of the same.

As best shown in Figs. 1 and 2, the machine comprises two tanks towit,thewashing-tank 15 and the rinsing-tank 16. Said tanks are supportedin a suitable frame formed, preferably, of angle-irons, as shown in Fig.2. Said frame may be of any suitable construction to support the partsofthe machine. As shown in Fig. 2, the upperedges of the tanks 15 16 arecoincident with the top of the frame of the machine, and a plate or tray17 is provided, which extends around the tanks and receives the watersplashed from the tanks or dripping from the baskets as they are removedfrom the tanks. A flange 18 extends around the tray 17, as shown inFigs. 1 and 3, to confine the water and conduct it to a drain 19, whichcommunicates with a waste-pipe 20, as shown in Fig. 1. I

21 indicates a drip arranged at the end of the frame nearest therinsing-tank 16 and adapted to conduct the drippings to the tray 17, asshown in Fig. 1.

22 indicates a basket-suspending frame, which is itself adapted to besuspended in the washing-tank 15, which frame serves not only to supportthe dish-holding basket when it is in the tank, but also carries thedeflectors by which the wash-water is directed upon and against thedishes. Said frame 22 is best constructed of two U-shaped bars 23,placed at right angles to each other and rigidly secured together, saidU shaped bars being connected at their upper ends by a ring 24, as bestshown in Fig. 7. A reinforcing-plate is provided, which is secured tothe lower portions of the bars 23, as best shown in Figs. 7 and 8. Ifdesired, instead of using two U-shaped bars 23 the number may be varied;but I have found that the best results are secured by using the two barsarranged as described.

The external diameter of the ring 24is equal to the internal diameter ofthe tank 15, so that said ring is adapted to fitsnugly inthe upper IOOportion of said tank, where it is supported by brackets 26, secured tothe inner surface of the tank, as best shown in Figs. 1, 2, and 3. Theframe 22 is thus suspended in the tank. To prevent the frame fromrotating in the tank, the ring 24 is provided with a notch 27, adaptedto receive a lug 28, projecting inwardly from the surface of the tank15, as best shown in Fig. 1. The bars 23 are long enough.

so that the bottom of the frame 22 lies, preferably, below the center ofthe washing-tank 15, as best shown in Fig. 2, the object being to carrythe dish-holding basket low enough so that the wash-water may properlybe directed down upon the dishes without danger of its splashing out ofthe tank.

29 indicates the deflectors, which, as shown in Fig. 7, are carried bythe frame 22. As shown, the lower ends of said deflectors are secured tothe bars 23 and their upper ends to the ring 24, the deflectors beingheld in an inclined position. The best results are secured by curvingthe deflectors 29 slightly, so that they are somewhat spiral in outline,as shown in Fig. 7. The width of the deflectors is such that when theyare secured in place their outer edges will be substantially in theplane of the periphery of the ring 24, so that when the frame 22 isfitted in place in the tank 15 the deflectors 29 lie substantially incontact with the inner surface of the tank 15.

30 indicates the agitator, the simplest form of which is best shown inFig. 9. It consists of a hub 31, having radial arms 32,which carrydeflectors 33 at their forward sides, extending from their outer endsinward about half the length of the arms 32. The deflectors 33 extenddownward and forward from the arms 32, so that as the agitator rotatesin the direction indicated by the arrow in Fig. 9 the deflectors willdirect the water up and also give the body of water a whirling motion.Owing to the fact that the deflectors 33 extend a considerable distanceinward from the outer ends of the arms 32, the upward movement of thewater is not limited to the outer portion of the tank, but the waternear the center is also directed upward, causing violent ebullition nearthe center of the tank. The water near the walls of the tank, however,rises to the highest point, owing to its more rapid movement.

The agitator 30 is mounted upon the upper end'of a shaft 34, carried inthe bottom of the tank 15, as best shown in Fig. 2, a set-screw 35 beingprovided for securing the agitator to said shaft. The lower end of theshaft 34 fits in a suitable socket 36 in the bottom of the tank 15, theupper portion thereof passing through a lubricator-box 37 and thencethrough astufflng-box 38, carried by the cover 39 of the lubricator-box,as shown in Fig. 2. The bearings above and below the lubricatorbox 37serve to hold the shaft 34 firmly in its upright position.

40 indicates a beveled pinion which is mounted upon and keyed to theshaft 34 with-' in the lubricator-box 37.

41 indicates a beveled pinion which is also mounted in thelubricator-box and meshes with the pinion 40. The pinion 41 is mountedon a shaft 42, which extends through a sleeve 43 in the bottom of thetank 15 into the lubricator-box 37, passing through a stuffingbox 44 inthe side of the tank 15, its upper end being fitted in a bearing 45, asshown in Fig. 3.

46 indicates a pulley mounted on the shaft 42 for rotating said shaftand through it the shaft 34. Instead of a pulley 46 a crank may beattached to the shaft 42 for rotating it, so that the agitator 30 may berotated by hand. By mounting the pinions 4O 41 and the shaft 34 in thelubricator-box they are not-only protected from dust, but are alsocontinually lubricated, as the lubricator-box, being filled with oil orother suitable lubricator, keeps them always in a perfect state oflubrication. It also deadens the noise of operation, so that the machinemakes no disturbance when operating. The shaft 34 is made as short aspossible, so that the agitator 30 will be carried as near as possible tothe bottom of the tank, and the lower portion of the suspending-frame 22is arranged to lie immediately over and adjacent to the agitator.

47 indicates the dish-holding basket, which is of wire mesh or otheropen-work construction and is adapted to hold the dishes to be washed.Said basket is slightly less in diameter than the suspending-frame 22,into which it is adapted to fit, resting on the bottom thereof, as shownin Fig. 2. The bottom of the basket 47 is of open-work construction, aswell as the sides, so that the wash-water may rise freely through it. 48indicates a bail by which the basket is carried. Said bail is providedwith upturned ends 49, adapted to book through slots 50 50 in lugs 51,rising from opposite sides of the basket. (See Figs. 4, 5, and 6.) Asshown in Fig. 6, the end of each lug is bent back upon itself and thensubstantially at right angles, the slot 50 extending through thevertical portion of the lug and also into the horizontal portion 52thereof. As shown in Fig. 4, the slot 50 also extends below thehorizontal portion 52, so that, as indicated by dotted lines in Fig. 6,the lower end of the bail may be moved down in the slot 50' until itlies in the slot 50 in the horizontal portion 52 of the lug. The bailwill thereby be held in a vertical position by the horizontal portion 52of the lug. By raising the bail, however, until it lies in the upperportion of the slot it will be free to rock. The object of thisconstruction is to hold the bail in an upright position when the basketis in the tank, thereby preventing it from being immersed in the water.

The operation of my improved apparatus as thus far described is asfollows: The tank 15 is partly filled with hot soapsuds, and the basket,filled with dishes, is then placed in the frame 22, resting on thebottom thereof. The shaft 42 is then set in motion, rotating theagitator 30 in the direction indicated by the arrow in Fig. 9. The waternear the center of the tank, as well as that near the circumferencethereof, is thereby thrown u p with considerable force, that nearer thecircumference rising until it strikes the under surfaces of thedeflectors 29, which directit downward upon the dishes in the basket. Atthe same time the water near the center of the tank is thrown updirectly through the bottom of the basket, meeting the water fallingfrom above, so that a very pronounced agitation of all the wash-water iseffected. This agitation is most violent through the space occupied bythe dish-holding basket, so that the water is forced through the dishes,which are thereby thoroughly scoured and cleansed. The best results aresecured by extending the deflectors 29 down a considerable distancebelow the upper edge of the dish-holding basket, as shown in Fig. 2, sothat part of the water is directed into the basket laterally through theperiphery thereof. The ring 24 in addition to supporting the deflectorsand the basket serves also to prevent the water from being thrown out ofthe tank, since any water which passes the deflectors 29 strikes theunder surface of the ring 24 and is directed back into the tank.

In Fig. 10 I have shown a more improved form of agitator, which issubstantially the same as the agitator 30, but in addition is providedwith a closed-sided cylindrical portion 53, secured to the ends of thearms 32, said arms being provided with lugs 54 for that purpose, asshown in Figs. 11 and 12. The deflectors 33 are also provided with lugs55 for further securing the cylinder 53. As shown in Fig. 2, thecylindrical portion 53 extends up between the bars 23 and the tank andserves to increase the agitation of the water and to direct it moreforcibly against the deflectors 29. It also aids in directing thewash-water thrown down by the deflectors 29 against the dishes in thebasket.

After the dishes have been washed the basket, full of dishes, is placedin the rinsingtank 16, which is filled with clean water, resting onsupports 61 62, as shown in Figs. 1 and 2, and after being rinsed thedishes are removed and placed on the drip 21.

56 57 indicate waste-pipes which, together with the pipe 20, communicatewith a pipe 58, adapted to conduct the waste water to the sewer. 59 60indicate pipes adapted to conduct hot and cold water to the lowerportions of the washing and rinsing tanks. All of said pipes areprovided with the necessary valves for regulating the supply of water tothe tanks or its discharge theref om.

In practice hot water or steam, or both, are continually introduced intothe rinsing-tank 16 while it is in use, so that said tank is constantlyfilled with clean rinsing-water, which overflows the upper edge of thetank and is discharged upon the tray 17, from which it passes throughwaste-pipe 20 to the sewer. As illustrated in Figs. 1 and 2, saidwastepipe 20 is not provided with any valves, so that the greasy waterflowing from the rinsing-tank, together with such grease as it mayaccumulate from the tray 17, is carried off, and as it does not come incontact with any valve mechanism the grease does not clog the discharge,as it would otherwise be apt to do. Moreover, the tray 17 is kept cleanby the overflow.
